Write me a bash script "ecs" that uses the aws cli to interact with aws ecs tasks supporting the following commands:

- ecs use <cluster>: Switch active cluster to <cluster>, store in ~/.ecs/context
- ecs get services: List services
- ecs get tasks: List tasks in cluster
- ecs exec <task> [-c container]: Run (interactive) command in container
